Fast response, emergency service
When you contact Westenn, count on fast response backed by an extensive fleet of over 12 service and install trucks. Your call will be answered by a live human being, not a voice mail recording, who will see that your needs are handled. We have someone on-call to provide emergency service, should you ever need it, 24 hours a day, 365 days a year. For our customers with larger, more sophisticated systems, Westenn even provides computerized monitoring capabilities, allowing limited remote adjustments. We can determine if a pump in a zone is down, or a boiler isn’t functioning properly, so we can address a situation before it turns into a major, costly problem.
